GMS fails to download vision libraries

[renclav]

Hi,

First off, thank you for your continued fast paced updates, never a dull moment in the Android world.

Attempting to run the multitracker example on my device fails as the GMS library download never completes with 'isOperational' always returning false. This occurs on both wireless and mobile networks.

The first thing to try is to free up storage space. How much free storage space do you have on the device?

Note that the download mechanism is a bit conservative, so as not to leave you in a state where you don't have much storage space left. If there is less than, say, 10% storage space remaining, it may not download those libraries (however, it doesn't actually use this much space).

Hi @pm0733464 ,

Creating space did solve the issue. With that in mind, could you please let me know if there are any plans to either

• Add callbacks to the library loading lifecycle
• Provide a mechanism to ship with the library bundle included with, perhaps as an added bonus, a means to update to the latest version via GMS

Thank You,
Dylan

[pm0733464]

Discussions are underway w.r.t. potential improvements to the downloading mechanism. We'll consider your suggestion on callbacks.

Bundling the library with the APK was something that we implemented internally, but chose not to include due to its drawbacks: (1) it would require developers to package/distribute multiple versions of their app for different hardware architectures, (2) every app using the functionality would have included the same library redundantly, using up space unnecessarily on the user's device, (3) it's not possible to update a bundled library via GMS.

[renclav]

Thank you very much @pm0733464 . I will be monitoring this lib closely and am looking forward to replacing our 3rd party versions. Unfortunately, without any lifecycle callbacks and/or resolution strategies (such as GCM), this has yet to become a viable production solution for our ecommerce apps.

I have same problem - Nexus 4 with 5.1.1 CyanogenMod 12.1, and GMS 8.3.0, over 1,1 GB free space, reliable Internet connection and still will always get "false" in "isOperational()".

The API to check if is working is poor (very less information) and as well callbacks would be nice.
